Popis:	In this study, Ba3SrNb2O9(s) was synthesized using conventional solid-state reaction route, characterized by powder XRD and SEM-EDAX. The standard molar enthalpy of formation of Ba3SrNb2O9(s) was determined measuring enthalpies of solution of Ba3SrNb2O9(s) in {PbO + B2O3} solvent (in 2:1 molar ratio) at T = 966 K using an oxide melt solution high temperature calorimeter. The enthalpy increment of Ba3SrNb2O9(s) was measured with same calorimeter. The heat capacity of the Ba3SrNb2O9(s) was also measured employing DSC. Based on the smoothed values of heat capacity, a table of thermodynamic data from 298 to 1000 K for Ba3SrNb2O9(s) was also constructed.
